Backflow from sewers has long been a problem in Hamilton.
It seems that after nearly every heavy rain event the municipal sewers become overwhelmed and homeowners all over town wind up with dirty water in their basements.
Thankfully there’s a pretty easy answer to this problem and it’s called a backwater valve.
A backwater valve is quite a simple concept, although it does require the expertise of a licensed plumber to install. In a nutshell, the backwater valve is just that: a valve that prevents water from backing into your home from the Hamilton sewer system. It’s a one-way valve that lets water out and prevents water from coming back in.
Disclaimer: Always wear protective gloves and eye protection.
A backwater valve is installed on the sewer line in your basement to prevent sewer lines from allowing water to flow back into the home. If properly installed, the backwater valve will only flow one-way; sewage can flow out, but not back into the home.
The Province of Ontario currently only approves of the Mainline Full port Backwater Valve for installation on the main sanitary sewer lateral of homes.
